Fran?ois, are you saying that in the callee side, the couldn't parse two media lines? It should. A print-out/Wireshark capture of the INVITE request would help here. I'll try to run it through the parser here. cheers Benny 2009/3/24 Fran?ois Roseberry <frank_pharaoh05 at hotmail.com> > Hi, > > We're using the PJLIB version 1.1 and PJMEDIA/PJSIP directly.
